Caractéristiques

Red giant in the constellation of Orion.

The volume differences between stars can be considerable (in a ratio of 1 million). Also, they are a function of the life cycle of the considered stars, for example a red giant is a star at the end of life (Betelgeuse or Antares).

The Sun is a small star.

The mass differences between stars remains in a ratio of approximately 1 in 150 (current theoretical limit).

Betelgeuse is 2500 degrees colder (red colour) and is 620 times the size of the Sun.
